To all whom it may concern/.-

Be it known that I, LOUIS Hemmer, a subject of the King of Saxony, and a resident of Zwickau, in the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in Steam-Generators for Motors for Sewing-Machines and other Operators for specification.

This invention relates to a steam-generator for motors adapted for the operation of various machines; and said motor consists in the construction and combination'of devices herehad to the accompanying drawings,in which Figure 1 shows a front view of the motor in connection with a machine, the eXa-mplctaken being a sewing-machine. Fig. 2 shows a vertical central section of the boilcr'on a larger scale than that of Fig. 1. Fig. 3 shows asection in the plane X Y, Fig. 2.

Similar letters indicate corresponding parts.

In the drawings, A represents a cylinder, the example taken being an oscillating cylinder, and B represents a boiler.

0 represents a lamp, which serves to heat the boiler and to give light. This lamp may be a petroleum-lamp, gaslamp, or any other suitable device.

The cylinder A in the example shown is arranged under the table of a sewing-machine,

crank-pin of the driving-wheel or fiy-wheel, which wheel thus serves as a common flywheel for the machine and themotor.

The steam-cond uit L is provided with a stopcock or closing device, E, which may be arranged on the table within easy reach of the operator, so that by closing said stop-cock the motor and the machine may at any moment be brought to a standstill.

The steam-boiler B is shown as arranged aboye thetable on a stand,so that the lamp 0, used for heating the boiler, will at the same time illuminate the object which is being operated on.

Figs. 2 and 3 show in detail. the construction of theboiler B. Theboiler B is provided of a tube located centrally in apendent extension of the boiler, which extension constitutes a water-leg, b. H of the lamp 0 may be made to pass. This arrangement insures a thorough utilization of heat, as the chimney H delivers its heat along its entire length to the water-leg of the boiler. The hot products of combustion pass out at the upper end of the recess a into the chamber (1, and from thence through a series of tubes or channels, 0, leading from said chamber (1 to the upper part or roof of the boiler, and into the open air.

A depression, f, in the roof of the boiler may serve for heating any desired object placed therein. To prevent radiation of heat the boiler is surrounded with a non-conductor of heatas, for example, felt. A reflecto1-,G, may he slid onto the lower part of the boiler B, and said reflector may be placed higher or lower, as desired, so as to illuminate the work which is being done. The arrangement and form of the channels a may be such as desired'as, for example, straight, spiral, or worm tubed.

The steam from the escape F may be led into a condenser or disposed of in any desired manner.

This motor offers several advantages,in that it enables the work operated onto be illuminated, and heats the room in which the work is being done. The motor can be easily adjusted 011 any machinefor example, a sew ing-machinewhere it is not obstructive, and allows the machine to be worked by the treadle D, if desired. The motor is also safe and economical, and does not require a separate attendant in addition to the one looking after the machine to which the motor is applied.

I am aware of patent to N. M. Simmons, May 18, 1877, No. 190,631, for liquid heater;

also the patent to J. Bowlein, December 17,-

1882, No. 133,918, for coffee-pot. My invention differs therefrom in the construction and combination specified in the following claims, by means whereof steam is not only generated, but provision is made for conducting it to a cylinder for use as a motive power, whereby the device is adapted to a use different from what the patented devices are susceptible of.

What I claim as new, and desire to secure by Letters Patent, isr 1. A steam-generator consisting of aboiler,

Into this recess a the chimney B,the bottom wall of which is constructed with a recess, a, in the form of a tube, extending into the waterspace of the boiler, and open at its lower end to receive a lamp-chimney, a chamber, (2, in the water-space of the boiler, into which the recess opens, tubes e,connected with said chamber, and open at their upper ends to the external atmosphere through the upper portion of the boiler, and a steam-conduit for connecting the steam-space of the boiler with a cylinder, and having a device, E, for closing the supply of steam, substantially as described.

2. A steamgenerator consisting of a boiler, B, the bottom wall of which is constructed with a pendent water-leg, b, a recess, 0, in the form of a tube, extended through the water-v leg for receiving the lamp-chimney H, a chamber, d, in the water-space of the boiler, connected with the upper end of the recess,tubes 2o 6, extending from said chamber and communicating with the external atmosphere through the top of the boiler, and a steam-conduit, L for connecting with a steam-cylinder.

In testimony whereof Ihave signed my name 25 to this specification in the presence of two subscribing witnesses.

LOUIS HEINRIOI.
